22 Foot Racing/Pocket Cruising Sailboat

You're not hijacking the thread. It's general information for those interested in this thread, a small racer cruiser and the last developments in the design of these boats.
That may interest Ned Lunav for his personal work.

I've made some search.
The "inventor" of these sailing monohulls with full bows is the naval engineer David Raison in 2009

It's maybe a bit dated as I found that in a internet site of Raison of 2011.

His designs are called in my opinion abusively scows. I have compared the lines of a scow to designs by Raison and the only thing common is the blunt nose. The water lines have little in common, and when heeling there nothing in common. Raison design purpose is to create a very powerful hull (28% more than a classic hull) , which keeps symmetrical water lines (isocarène), the daggerboard and the govern staying aligned. The hull has less tendency to bury the bow and no water runs over the deck. Fact which can compromise the stability and security. The IMOCA 60 feet are plagued by these problems of disymmetric water lines, buried bow and one ton of water running on the deck to the cockpit.

The top speed of a mini 6.50 is the same for the blunt bow and the classic bow around 18-20 knots. But there is a main advantage the blunt bow has a better mean speed and attain it easily and rather surely. The mean speed of the winner of the 2017 race is 7.55 knots, crossing the Atlantic from the Azores to the Antilles. It's properly fabulous for such a small boat.
During a race this year crossing the Channel from France all the head group spent a whole night at 15 knots mean speed...

A cruiser won't be pushed as hard as a racer but the speed potential is there. There is another advantage the blunt bow hull is pretty voluminous giving lots of space.
Nothing comes free. The blunt bow has more wetted surface and has a disadvantage in light weather . For a cruiser the solution is simple more sail...

Raison has co-designed an almost 24 feet the Rêvolution 22 Nouvelle Génération, a cruising tank in aluminium pretty interesting

A nice run, very relax on a 6.50 mini POGO 3 a classic bow cruiser racer, with an excellent record. You can buy this model at the shipyard for around 50000 USD.

 

Alone on a 6.50 mino around the world no scale, no stop, no assistance by the 3 caps in 268 days in 2012. That's a man Alessandro Di Benedetto.

 

Another NA (and racer) of mini blunt bow.

You have a lot of information in this page about materials and weights.

The design shows its age. The curves are nice but that lacks of volume, thus power. The last designs have more volume as the topsides form a hard chine with the bottom, giving more volume on the sides (and more habitability). Besides the keel lines are now tenser and flatter, the masts have moved to the aft, the mainsail being more multihull like, the gennakers and jibs are bigger.


The evolution in 25 years. Lines have changed a lot on the classic bows.

 

Thanks for the info llanVoyager

The vector 6.5 is quite an attractive looking boat for a scow.

I'd like to build one (when my current build is finished) however incorporate some modifications to make it trailerable on public roads (liftable keel and beam at 2.5m).
I think would make a good allrounder (club race, cruise/overnight, cheap to run, seaworthy)
Over here in Australia (it is a big country) something trailerable, opens up a lot more opportunities for new cruising destinations/experiences.

up until the Seascape 24/27, there weren't many options for a high performance trailer sailer which also looks 'modern'.

The French look to have these mini's dialled in after decades of development.
The performance figures are impressive for a small boat as you mention.

 

I have found more information about the Rêvolution 22 a very interesting little cruiser with blunt bow
1- a video with the renderings


2- a video of the method of building (formed thick aluminium plates 6 mm for the hull, 5 mm for the deck with minimal structure. It's a tank....), nice images of the interior. The inside volume is astonishing...

There is a lot of mental food to chew and assimilate in these videos. A look at the mast is very interesting. I would say that a naval engineer's design with lots of experience of the mini class.
Although being rather heavy and voluminous for comfortable family cruising it sails pretty well at very decent speeds.
